Pastries that are made from a batter and" cooked by coming in contact with a hot cooking surface have characteristics which are.

' facts and'propose to provide a pastry produse which is designed to cook merely a single not such as above noted, namely, a wafie, which is designed to act primarily as a jacket for food stufls, having the hot Wiener particularly in mind. This invention therefore has as its principal object, the provision of a cooking iron which will produce batter products o a new shape and which shape imparts to the said products the ability to act as a jacket or container ior food studs.

In carrying out this idea more in detail, my aim is to provide a waffle iron which will produce semi-concave waflles, two of which;

ma be employed conjunctively to form a jac et for a hot Wiener, or else one of which may be used as a container for food such as creamed chicken, etc. Under the last mentioned condition of usage, the wafle would referably be served with the concave side acing the serving platter, whereby pleasing appearance efl'ect is rovided. Also the wafie is adapted for t e reception of any dressing as butter, syrup, etc. due to the formation of the usual recesses in the exterior surfaces thereof. Inasmuch as mercial conditions point to the actthat the greatest possibilities of such a food product as it propose to provide are associated with" the hot Wiener field, a more particular object oi" the invention is to provide a wafie iron which will make the semi-concave wafies in airs, each pair providing the complete jacket or a sausage. At this point it might be well to mention that my invention has at least two distinct embodiments,a wafile iron for home pair of waes, and the iron which is intended for commercial or restaurant use which is capable of cooking several pairs oi jackets simultaneously. in the latter form,

resent comindependent heat controls for each set of molds are provided.

Ever since the wafile has been known as such, it has been characterized by the'fact that it has a surfacii having cle ressions therein, the depressions being cause by projections on the cooking metal which project from the mold. Such an arrangement insures the proper cooking of a waflie because it provides fer a condition wherein none of the atter is spaced so far from the cooking metal that it will not be properly cooked in a short time. Such arrangements are ood practice and I do not intend to depart. om them in providing my novel waffle iron. However, in view of the fact that my iron is designed to produce semi-concave Waflies and these waiiles are to be formed with depressions as is conventional, a particular object of the invention is to so arrange the projections on the cookin' metal of the molds, that the waflies in coo ed condition may be readily removed. Such would not be the case were the projections merely indiscriminately arranged on the molds.

Another feature of the invention of no little importance, is the provision of an iron including mold members which will form waflies in pairs, each wafie of which is complemental to the other, and which wafiles that are formed by the molds will include means interlocking them together, whereby they are rendered more adaptable for use as a jacket of a hot sausage. With this end in view, each of the wafies' is formed with recesses and lugs properly disposed so that they will cooperate with comemental recesses and lugs on the it prevent relative movement other we e to therebetween.

With these and other objects in view as will in part become apparent and in part be hereinafter stated, the invention comprises certain novel constructions, combinations and arrangements of parts-asfivill be subsequently specified and claimed. For a full and more complete understanding of the invention, reference may be had to the following description and accompanyini drawings, in whichigure 1 is a view in side elevation of an till various embodiment of my. invention which is designed primarily for home use.

While a preferredspe'cific embodiment of the invention is here shown, it is to be understood that I am not to be limited to the exact constructions and illustrations because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims. Y

Throu hout the following description and figures of the drawings, like reference characters denote corresponding parts. First referring to Figures 1, 2 and 3 which illustrate the type of iron designed for home use, it is noted that the iron comprises "the mold portion consisting of the members A and B and the pedestal or stand portion X. The stand X' may include foot members 1 which maintain the same upraised from the surface on which the iron is set. For car-. rying the entire wafiie iron from place to place, the lower mold member A is provided with the handles 3 so that the iron may be lifted in its entirety and carried from place I to place.

In the present embodiment heating means for heating the molds areprovided in the form'of electric'heat resisting elements. For connecting these heatin elements with a current supply line a suitabTe connection is shown at 4. Of course any suitable heating means may be employed with the molds as circum-- stances dictate. They may be heated by-coal, gas, oil, etc.

The mold members A and B are hinged together by the hinge members 5 secured to the mold members by the screws 6 and which are provided with lugs'7 which function both as guides and as stops for limiting the'swinging movement of the top mold member. The top mold member B is provided with a hendle properly positioned to facilitate the opening swin ing movement of this member.

For a detailed understanding of the inteare provided with the lugs 11 and recesses 12' I which form complemental recesses and lugs in the wafies formed by the molds. The

member C also has the projections 13 provided with ribs 14 which function to shape the cavity in the waffle cooked by the iron.

The lower cooking member D is of course formed with the two main recesses shown at 15 which are adapted to receive the parts 13 carried by the member 0 but which parts will be spaced from the member D when the 4 iron is in cooking position. Extending into the cavity in the member D are projections 16, the particular arrangement of which is clearly shown in Figure 7. These projections are all vertically disposed so that they will not interfere w1th 'the removal of a cooked waffle from the mold. In further pursuance of obtaining an easy removal of a waflie from the mold theprojections 16 are formed in a certain shape which readily lends itself to the achievement of the desired end. The end of each of the, projections is of an arcuate shape, the curve of which is substantially the same as the curve of the upper face of the mold. When one half of the mold is lifted no binding action occurs which normally would be the case were not the projections shaped as above noted and vertically disposed. This arrangement insures the condition of having all of .the batter in close proximity to some heating metal whereby the same is properly cooked. The heating instrumentalitles employed may be briefly described as follows :Spaced plates 17- are fastened to the. molds G and D by means of screws as shown at 18. Interposed between the spaced plates 17 are heating elements 19 which are connected together by wires 20. The wires 20 are'then brought to the plug 4 thereby providing a means for heating the molds C and D. A flexible tube 21-covers the wires 20 between the parts A and B as shown in Figures 3 and 6.

, The commercial embodiment of the invenhandle 22 is provided for the upper member B of'each unit, which is also provided with a heat controlling switch shown at23. Wires 24 set up the connection between the heating elements and the switch to provide the variable heat essential to the proper operation of the iron. The plug 26 provides a means for connecting the cooking members with the main current supply line.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is
